Turn signal: What is that device? Just wondering. I have always thought for as long as I have been driving that it was a vehicle violation and a person could be cited for not using a turn signal. I guess what with the use of cell phones and texting, which last I heard was also a violation, and people just being too lazy to lift their left hand a couple of inches from the steering column, that using a turn signal is a lost art. Or is it just me?
